    II. KEDAH PEAK

    P. Tixier*

    Kedah Peak (Gunong Jerai, 1,350 m), an isolated hill above the rice fields and near the sea, is at about forty kilometers South of Alor Star, the chief town of the Kedab State.

    One may think that the massive rocks are granitic. Dr. B.C. Stone of the University of Kuala Lumpur notes the ressemblance between this mountain and Mt. Bokor in Cambodia on the border of Thailand Gulf.

    This two stations are situated just above the sea shore and received directly the South-East moonson. Yet some difference may be noted: the Bohor is a wide plateau of about 30 km long, between Kampot and Sre Am bel and it is probable that its vegetal formations occupy all the mari-time front of the Cardamones Range till the Thai border. On the other hand, Kedah Peak remains a regularly sloping massive of only 10 km in length and without any connection with other hill ranges; its slopes come steeply down to the sea and the plain.

    The two stations have a real dry season but the Bokor is probably wetter than the Kedah Peak because its annual rainfall is 3-4,000 rom, but only 2,000 mmjyear in the Kedah Plain.

    Considering the orientation of the massive, the southern and the northern faces are drier, the other ones wetter.

    There are no real different levels of vegetation along the slopes. The lowland forest remains poorly known botanically, and from the sea-side, the first formation is the mangrove forest.

    Some species of palms are found in the understorey of the dense forest. The most characteristic formations of the massive are seen on the western face (deciduous forest) and on the top of the bill (shrubby forest).

    Deciduous forest formation remains a little mysterious and it seems

    probable that the forest should be really secondary, in fact I prefer an

    edaphic origin to this formation growing on eroded soils with big boul-

    ders.

    Coarse herbaceous species cover the ground (grasses, sedges, ferns)

    similar to those occurring in Bokor at Popokveal. The following bry-

    ophytes form cushions on the soil: Sphagnum junghuhianum, Leucobryum

    javense, and Mastigophora diclados.

    On trees one can recognize following orchids: Sarcopodium spp., Bul-

    bophyllum spp ., Eria spp., and Acriopsis indica. In addition there are a

    good lot of epiphytic Asclepiadaceae ( Dischidia nummularia, D. pseudo-ben-

    galensis, and D. rafflesiana) and also Hydnophytum sp., a myrmecophi-

    lous plant.

    The forest on the top is more a crest forest than a real shrubby formation as that known from Bokor. There are no big trees above the canopy of the formation and the forest appears less impenetratable than

    in Bokor. In the crest forest, the epiphytes and the epiphylls remain in the lower stratum. The bryophytic carpet (mosses for the greater

    part) covers the soil and the base of the trunks. Epiphyllous liverworts do

    not get beyond one meter from the ground and it is the same for the

    orchids, such as Eria velutina, Podochilus sp., Dendrobium revolutum and

    some species of Bulbophy llum.

    CONCLUSION

    The community floristic coefficients between Kedah Peak and eleven regions in Tropical Asia, Malesia, Melanesia and Pacific islands are established basing on the mosses and liverworts as enumerated in this list. The value of C.F.C. may be proportional to the distance bet-ween Malaya and the region considered. This is more evident in mosses than liverworts; but the knowledge of the latter is poorer than of that of mosses. It can be remarked that New Caledonia and Ceylon bas the same C.F.C. For a bryological point of view, the tropical Asian-Ocea-nian world is continous from the beginning of wet regions (Ceylon) to the end of the warm ones (New Caledonia, Noumea, average temperature, 20"C). It seems probably that, the regional divisions based on the bry-ological elements, are closer to reality than that based on the phaneroga. mic plants.
